Vibration-based health monitoring of aero-engine bearings . This project will develop new vibration-based techniques to greatly improve the detection and diagnosis of faults in aero engine bearings from in-flight measurements.

This project will develop new vibration-based techniques to greatly improve the detection and diagnosis of faults in aero engine bearings from in-flight measurements. To achieve this goal, advances will be made on source separation algorithms to extract the weak bearing signals, and signal processing techniques to extract features for diagnosing bearing fault severity and lubrication conditions, under a wide range of operating conditions. A bearing degradation model will estimate the remaining useful life. Since rolling element bearings are among the most critical components in most machines, the results of this research will also provide massive benefits in other sectors such as mining, transportation, energy production and manufacturing.Read moreRead less
A new role for vibration analysis in gear wear modelling and prediction. This project aims to improve prediction of the remaining useful life of gears. Gears are widely used in industry and transport. This project aims to integrate the two main methods of gear condition monitoring, vibration and oil analysis, and perform model-based wear prediction with the tribology and dynamic models continually updated on the basis of measured wear debris and vibration. New signal processing tools should allo ....A new role for vibration analysis in gear wear modelling and prediction. This project aims to improve prediction of the remaining useful life of gears. Gears are widely used in industry and transport. This project aims to integrate the two main methods of gear condition monitoring, vibration and oil analysis, and perform model-based wear prediction with the tribology and dynamic models continually updated on the basis of measured wear debris and vibration. New signal processing tools should allow estimation of relatively weak friction forces, previously neglected, as an important prognostic tool. This would allow detailed root cause analysis and prediction of remaining useful life. Improvements in gear prognosis would have safety and economic benefits by eliminating unforeseen catastrophic failures and optimising maintenance schedules.Read moreRead less
A physically based abrasive wear model for high-speed steel at high temperature. The economic benefits of reducing roll wear, extending roll life and improving strip quality are very significant. This comprehensive project will provide new knowledge on tool wear to help the Australian manufacturing industry (e.g. steel and aluminium, machining) to better understand and optimise their processes to achieve maximum benefits.
A smart functional lubricant for hot strip rolling. This project aims to develop a new generation smart lubricant system through an innovative polymer micro-encapsulation strategy that allows in-situ creation of hierarchical coating before rolling and during hot rolling contacts. This coating is expected to deliver the integrated lubrication and functions to suppress secondary and tertiary scale growth while providing effective lubrication during the hot rolling. This project will make a signifi ....A smart functional lubricant for hot strip rolling.

This coating is expected to deliver the integrated lubrication and functions to suppress secondary and tertiary scale growth while providing effective lubrication during the hot rolling. This project will make a significant contribution to improved product yield, prolonged service life of work rolls, better strip surface quality, and overall improved process efficiency.Read moreRead less
A tribological approach to improve surface quality of silicon steel. This project aims to design a lubricant composite where multiple additives work in synergy and perform at high temperatures. In hot rolling of silicon and electrical steels, significant surface defects of red scales, severe work-roll wear and high friction are problems for traditional lubricant which cannot perform effectively under extreme thermal/loading conditions. The new lubricant is expected to eliminate red scale defects ....A tribological approach to improve surface quality of silicon steel.

In hot rolling of silicon and electrical steels, significant surface defects of red scales, severe work-roll wear and high friction are problems for traditional lubricant which cannot perform effectively under extreme thermal/loading conditions. The new lubricant is expected to eliminate red scale defects, reduce oxidation and rolling force, improve surface quality and extend roll service life.Read moreRead less
